How the Zergs were Made

Chapter 50: Ice

The comet rapidly enlarged at a speed visible to the naked eye, and then swept past at a high speed at a distance of nearly ten kilometers from the cell cluster.

When Huogu realized it, the distance between the comet with a diameter of tens of kilometers and the planet was only 300 kilometers.

With the high speed of the comet at this time, if there is no accident, it will hit the surface of the planet at a circumscribed angle under the traction of the planet's gravity in a few minutes at most.

So far, everything that happened was normal. Although the appearance of the comet was a little unexpected, it was the result of Huo Gu focusing on searching for the unknown enemy and subconsciously ignoring it.

However, the next second the world began to be abnormal.

A source of strong gravitational force appeared out of nowhere, so abruptly and without warning.

At the same moment, the cluster of cells also slipped out of orbit as it lost its gravitational bond from the star.

This gravitational point cannot be seen, but it can be felt. Through the force deformation of the cells in the titanium alloy carapace and the comparison data of the planet, Huogu can roughly obtain some information about the gravitational source—the gravitational source and the planet, the gravitational strength is equal, and the space The location is different.

Observing from the perspective of a bystander, it is as if the center of gravity inside the planet suddenly jumped out of the inside of the planet.

This phenomenon of gravitational point transfer lasted only a few seconds, but it was enough. The comet that was supposed to hit at a circumscribed angle was dangerously separated from the troposphere and stratosphere on the surface of the planet. The separation zone passed by at a distance of about twenty kilometers.

During this passing process, the comet disintegrated, and the comet with an average density of only 100kg/m^3 had already exceeded the Roche limit of a rigid body between it and the planet, breaking into five pieces with a diameter of ten kilometers to Comet fragments between five kilometers.

However, since its own speed is far greater than the gravitational escape velocity of the planet where Hogu is currently located, even if the comet disintegrated, the fragments did not fall to the surface, but passed by the planet and parted ways.

After a long time, Huo Gu woke up like a dream, not knowing what words to use to describe what he saw.

The line of sight moved back and forth at the position where the planet and the source of gravity had appeared, and some kind of horrifying thought came out of it.

"Could that thing be..."

"Not good! The height is falling!"

Due to the gravitational disturbance just now, the cell cluster deviated from its original orbit and fell towards the planet.

At this time, the matter of the source of gravity was temporarily put aside, and Hogu needed to deal with the matter at hand first.

When the command was issued, the cell cluster with the appearance of a cone turned its body, with the sharp head facing the starry sky, and the tail facing the surface of the planet, and the balance wings on both sides of the shell stretched out.

Since the enemy is not in space, there is no need for Hogu to pay attention to space for the time being, but before that, Hogu needs to recover the cell clusters that were launched into outer space.

Huogu didn't intend to give up this cell cluster, which was inconsistent with its principle of action, even if the opponent was just a biological tool.

The falling speed is getting faster and faster, the air rubs against the titanium alloy shell, and the long column of flames wraps the cell clusters, just like the scene when it was launched into space, but this time, it returned to the surface.

With the cell cluster still more than 30 kilometers away from the surface, the propulsion ignition jet at the tail immediately slowed down the falling speed of the cell cluster a lot.

Subsequently, an airbag at the top of the cone is deployed, and the other end of the airbag is connected with liquid hydrogen as a fuel. Under the normal atmosphere, the liquid hydrogen is quickly converted into hydrogen gas, and the airbag is filled to the limit.

As a result, the speed of descent was further slowed down. With the strength of the titanium alloy shell, the speed at this time could no longer cause any danger to the cell cluster, and Huogu could also shift his mind to other things.

Hostile whirlwinds, lava, and lightning are still raging on the planet, destroying the rhizome system.

The unknown existence's attack on the rhizome system lasted for quite a long time, even without Huo Gu's obstruction and interference.

Because the original plan had been planned for a long time, with an extremely large layout area, organic material reserves in units of 'billion', and various attacks were conceived in advance, and targeted defenses were made.

Huogu didn't respond immediately, it was just observing. With regard to the true face of the enemy, Huogu already had a general idea based on all the previous information.

It's just that this idea is so unbelievable that even its proposer is hard to believe.

Moreover, this kind of conjecture, there are still some places that are difficult to explain, such as the enemy's hostility to giant biological tools such as the rhizome system and the octahedron.

Just when Huogu formulated a new test plan to confirm his guess, a certain abnormal situation on the planet caught Huogu's attention.

First of all, the rain stopped and the dense cumulonimbus clouds cleared away. From then on, the day of this planet is no longer chaotic, without any reference, but divided into day and night.

During the day, you can see the stars rising slowly, the big brothers in this planetary system.

In the dark night, there is no light pollution at all, and the starlight in the sky will make the night less deadly.

This indicates that the early rain sea generation period of this planet is over.

At the same time, taking the opportunity of the previous comet passing over the surface of the planet, the global temperature began to drop sharply.

The source of all this is the battle between Hogu and the unknown enemy, as well as the five comet fragments that had escaped and were dismembered by tidal force due to Roche's limit.

In order to maintain its huge shape, the octahedron relies on muscle cells all the time, consuming a huge amount of methane in the atmosphere, which leads to a sharp drop in the concentration of methane in the atmosphere, which keeps the planet at a constant temperature, and is the fundamental reason for the cooling of the planet.

Although carbon dioxide is also a greenhouse gas, its own properties allow it to dissolve in water or be converted into oxygen by oxygen-producing microorganisms, so carbon dioxide cannot fully play the role of 'insulation'.

Although the comet is just passing by, its low temperature still creates the same effect as a 'fuse'. Under the action of the 'fuse', the 'cause' transitions to the 'effect', just like the collapse of dominoes. A slight change appeared, and Zhang Qiang soon expanded, becoming out of control.

Of course, these are not the point, the point is the changes that are taking place on the planet, unusually fast, like a video tape being fast forwarded, day and night like a light switch played by a child, high frequency flickering Suddenly dark.

It took a long time for Huogu to throw away his understanding of what the current situation is—his perception of time is slowing down.

The temperature dropped further. In Huogu's view, the ice on the sea surface was like weeds, 'growing' everywhere, and soon declared the hegemony of the sea and land. Icebergs rose up on the ice, almost It's like being in a virtual game world.

The last scene Huo Gu saw was the extremely cold world covered in snow and covered in snow.

After that, the darkness came from behind, as if falling into a bottomless black hole.
